⚡ Explorers: The Interruption

A fully interactive A2.2 Kids grammar lesson that teaches interrupted past actions with a memorable sandwich visual. Explorer Club masters learn that a long background action (was/were + -ing) is the bread and a short sudden action (past simple) is the bite, joined by 'when'. The language focus has three blocks: The Sandwich Sentence (I was sleeping when the phone rang, with a formula and a when/suddenly/at that moment/while signals panel), Flip It Around (both orders work, and a comma is needed when 'when' comes first), and Which Verb Gets -ing? (a five-row table separating the long continuous action from the past simple interruption). Ten words (interrupt, suddenly, moment, rang, knock, drop, notice, scream, appear, shadow) appear in a scrollable table with kid-friendly definitions and examples, and six get review flashcards. The reading is a 125-word camp story — A Noise in the Dark — where a quiet evening is interrupted by a knock that turns out to be a hungry rabbit, with eight hover-tooltip words and both 'when' and 'while' sentences in context. Practice offers eight contextualised fill-in-the-blank items (when, while, was/were, -ing and past simple forms, and a lesson word) with live green/red validation, hints and a running score. Speaking gives five 'when story' prompts and a model five-line dialogue where the explorers swap real interruptions. The writing task asks learners to describe one real interruption in 30–50 words with a four-point checklist and a live word counter with auto-save. A full eight-question quiz blends the interruption grammar (when, long vs short action, past simple bite, correct sentence choice) with two reading-comprehension questions, offering a progress bar, per-question explanations, a result circle and localStorage persistence.
